This paper explores the critical issues faced by hydraulic systems in heavy trucks
used in mining operations. It discusses common problems such as hydraulic fluid leaks,
contamination, overheating, and pump or valve failures, emphasizing their impact on
truck performance, safety, and overall operational efficiency in harsh mining
environments. The paper highlights how environmental factors like dust, extreme
temperatures, and heavy loads exacerbate these issues, leading to increased downtime
and maintenance costs. It also provides practical solutions, such as regular system
maintenance, improved filtration, effective cooling, and better operator training, to
mitigate these problems and enhance system reliability. Ultimately, the paper
underscores the importance of addressing hydraulic system failures to maintain
productivity and reduce the risks associated with equipment breakdowns in mining
operations.
